Investigating the Impact of Different Loading Patterns on the Permanent Deformation Behaviour in Hot Mix Asphalt

This research was conducted to evaluate the effect of different loading combinations on the permanent deformation behaviour in asphalt mixtures. Therefore, repeated loading permanent deformation test was performed considering different stress levels, loading durations, rest periods and testing temperatures. The results showed that the slope coefficient of Power-law model has a more influence on permanent deformation compared to intercept. Moreover, rutting zones are sensitive to testing parameters. Rest period could significantly affect the first zone. Nevertheless, secondary zone depends on the loading duration and deviator stress. Eventually, the testing temperature has the greatest influence on the permanent deformation behaviour.
